Hi deadarius
You wouldn't have the application called "Magicprefs" installed, would you? I've experienced this problem myself, it started when i updated to OS X El Capitan and it seems to be directed towards some applications, namely the one i stated, that prevents keychain dialogs from being accepted. If you have it installed, please try to close it and try again, if not then perhaps you may have another software which triggers the same behaviour.
